Hi there, As an example, I have tried to integrate JSch into J2MEVNC, which is GPL'ed VNC viewer at http://j2mevnc.sourceforge.net/ . After some tiny hacks, it seems it works at least on Sun's Wireless Toolkit simulator. If you are interested in this hack, please refer to http://sourceforge.net/forum/forum.php?thread_id=1218089&forum_id=262224 Thanks, -- ymnk |

Hi there, The source code for J2ME/MIDP2.0 is available at http://j2me.jsch.org/jsch-0.1.17-J2MEMIDP20-20050124.zip and also an example for the remote execution on SSH2 is released. Thanks, -- ymnk |

Hi, +-From: "Michael Comeau" <mi...@br...> -- |_Date: Wed, 19 Jan 2005 11:22:27 -0500 ____________ | |Our platform is a customized version of Linux using the 2.4.25 |kernel on an AMD AU1100. This is used on a handheld vehicle |diagnostic device we built for DaimlerChrysler. |As stated, the JVM is Esmertec's Jeode/JBed (formerly Insignia's |Jeode). This JVM is a CDC Personal Profile implementation. Thank you for your info. |All of my testing thus far has been with the JCTerm application. |I have also tested on the PJava implementation of Jeode on the |same platform. JCTerm hung after prompting for a password. I |have not yet debugged the problem. If I get it running I will let |you know. I had a similar problem in running JSch on SHARP Zaurus PDA, where Linux kernel is running. In that problem, it had seemed that jsch had hung-ed, but I had found that it just had taken too long time to generate random numbers. I guess entropy pool for random numbers included in Linux kernel is empty. To work around this problem, I tried to use java.security.SecureRandom class from BC lightweight API and the problem has disappeared, but I had to obfuscate the jar file. Thanks, -- ymnk |

Hello Atsuhiko, Thank you for your assistance. We are so far very pleased with JSCH for J2ME. Our platform is a customized version of Linux using the 2.4.25 kernel on an AMD AU1100. This is used on a handheld vehicle diagnostic device we built for DaimlerChrysler. As stated, the JVM is Esmertec's Jeode/JBed (formerly Insignia's Jeode). This JVM is a CDC Personal Profile implementation. All of my testing thus far has been with the JCTerm application. I have also tested on the PJava implementation of Jeode on the same platform. JCTerm hung after prompting for a password. I have not yet debugged the problem. If I get it running I will let you know.

Hello Atsuhiko , I had discovered this problem when I was tracing through the JSCH source code. I was originally using an updated version of BouncyCastle's lightweight API that I downloaded directly from the BouncyCastle website. It does not contain a LICENSE class. When I used the BouncyCastle API zip files that are provided with the JSCH J2ME implementation everything works fine. My question to you, why check for the LICENSE class if the BouncyCastle lightweight API is free with no license restriction (see below)?

Hello again,
I have only the default SUN provider entry in java.security.
I have included only the following on the CLASSPATH:
jsch-0.1.17-j2mecdc-32.jar midp_classes.zip midp_crypto.zip
Yet, when I run the JCTerm application I receive the following error:
connect: random java.lang.ClassNotFoundException: com/jcraft/jsch/jce/Random
java.lang.NullPointerException
at com.jcraft.jsch.Session.send_kexinit (bytecode 48)
at com.jcraft.jsch.Session.receive_kexinit (bytecode 69)
at com.jcraft.jsch.Session.connect (bytecode 693)
at com.jcraft.jsch.Session.connect (bytecode 5)
at com.jcraft.jcterm.JCTermJ2MECDC.run (bytecode 291)
at java.lang.Thread.run (line 10)
It looks like the com.jcraft.jsch.Session class included in the
jsch-0.1.17-j2mecdc-32.jar
was built to use the com.jcraft.jsch.jce package.
I have all of the sources and have built them. If you can tell me what I
need to update to
make use of the com.jcraft.jsch.bc package I will make the change and
rebuild.
Thanks,
Mike

It seems wrong jar has been included in CLASSPATH.
http://j2me.jsch.org/jsch-0.1.17-j2mecdc-32.zip has not included
'com.jcraft.jsch.jce' package and it should refer to
'com.jcraft.jsch.bc' package. May I ask you to add
http://j2me.jsch.org/jsch-0.1.17-j2mecdc-32.jar ?
|Do I need to make an entry in the java.security file for the

It will only use BC's lightweight API, so you don't have to modify
java.security file.

Hello Atsuhiko,
Thank you for responding.
When I remove the SUN JCE components, so that only the JSCH J2ME jar and
the BouncyCastle zip files are in the CLASSPATH the following error occurs.
java.security.NoSuchAlgorithmException: DH KeyPairGenerator not available
Exception in thread "Thread-0", java.lang.NoClassDefFoundError:
javax/crypto/spec/DHParameterSpec
at com.jcraft.jsch.jce.DH.getE (bytecode 7)
at com.jcraft.jsch.DHG1.init (bytecode 172)

at com.jcraft.jsch.Session.connect (bytecode 5)
at com.jcraft.jcterm.JCTermJ2MECDC.run (bytecode 291)
at java.lang.Thread.run (line 10)
Do I need to make an entry in the java.security file for the BouncyCastle
provider?
I did find a reference on the BouncyCastle Web site to make the entry,
however I do not
know what class name to refer to.
Regards,
Mike

|Hi, I am attempting to get JSCH for J2ME running on an embedded
|MIPS/Linux platform using the Jeode J2ME JVM by Esmertec.
I think that Jeode J2ME JVM by Esmertec is CDC. Is it right?
|I am getting the following error when running the JCTerm sample.
| java.security.NoSuchAlgorithmException: SHA1WITHRSA Signature not
available
I guess you have tried
http://j2me.jsch.org/jsch-0.1.17-j2mecdc-32.zip
That jsch for J2ME/CDC will not use JCE and only depends on BouncyCastle's
lightweight cryptography API.
|My CLASSPATH variable contains the following:
|/app/jsch/lib/US_export_policy.jar:/app/jsch/lib/jce1_2_2.jar:/app/jsch/lib
/jsch-20050117.jar:/app/jsch/lib/local_policy.jar:/app/jsch/lib/midp_classes
.zip:/app/jsch/lib/midp_crypto.zip:/app/jsch/lib/sunjce_provider.jar
So, may I ask you to delete JCEs and only add BC API, which is available at
http://www.bouncycastle.org/download/lcrypto-j2me-125.zip ?
Thanks,
